Description

本発明は、電槽の外部側面にリブが形成された鉛蓄電池に関する。   The present invention relates to a lead storage battery in which a rib is formed on the outer side surface of a battery case.

従来、鉛蓄電池は、鉛を主成分とする正極基板および負極基板にそれぞれ正極活物質および負極活物質を充填してなる正極板と負極板とをセパレーターを介して交互に積層し、同極性同士の極板の耳部を溶接によって接続することにより極板群を形成し、前記極板群を電槽箱に収納し、この電槽箱に注液や排気用の開口部を有する電槽蓋を溶着あるいは接着剤で接着し、この開口部から電解液を注液し製造した鉛蓄電池が知られている（例えば、特許文献１参照）。この種の鉛蓄電池は、標準の外形寸法が規格化されている。そのため、電槽箱に収容する電極板の枚数に応じて、電槽箱本体の内部空間を制限し、電槽箱の外形寸法を規格寸法にそろえるために、電槽箱本体の外部側面にリブを形成している。
また、電槽箱本体の外部側面に縦リブを複数本形成し、該縦リブの幅寸法を中央では大きくし、側部に行くほど小さくすることで、電槽の強度向上を図ることが知られている（例えば、特許文献２参照）。 Conventionally, a lead-acid battery is formed by alternately laminating positive and negative plates obtained by filling a positive electrode substrate and a negative electrode substrate containing lead as a main component with a positive electrode active material and a negative electrode active material, respectively, via separators. The electrode plate group is formed by connecting the ears of the electrode plate by welding, the electrode plate group is housed in a battery case, and the battery case lid has openings for injecting and exhausting the liquid in the battery case A lead storage battery manufactured by welding or adhering with an adhesive and injecting an electrolytic solution from this opening is known (for example, see Patent Document 1). This type of lead-acid battery has standardized outer dimensions. Therefore, in order to limit the internal space of the battery case body according to the number of electrode plates accommodated in the battery case, and to align the outer dimensions of the battery case to the standard dimensions, ribs are provided on the outer side surface of the battery case body. Is forming.
In addition, it is known that a plurality of vertical ribs are formed on the outer side surface of the battery case body, and the width dimension of the vertical ribs is increased at the center and decreased toward the side to improve the strength of the battery case.

ところで、この種の鉛蓄電池は、輸送時には、複数の鉛蓄電池を並べてパレットに載置して緊締し、梱包されている。しかしながら、縦リブが電槽蓋の周側面より突出しないように形成されているため、輸送時に振動を受けて、鉛蓄電池が移動し、隣接する鉛蓄電池の電槽箱本体の外部側面に設けられた縦リブが、互いに隣接するリブ間に入り込みリブ同士が噛み合ってしまう事が考えられる。輸送時に、隣接する鉛蓄電池のリブ同士が噛み合った場合には、隣接する電槽箱本体はリブ同士が噛み合った分、互いに近づく。これに対して、電槽箱の開口部を閉封する電槽蓋は、上面視で鉛蓄電池の規格寸法に形成されているため、隣接する鉛蓄電池のリブ同士が噛み合った場合でも、互いに近づくことがない。そのため、電槽蓋に対して、電槽箱の下部が隣接する鉛蓄電池同士で近づき、鉛蓄電池が傾いて、パレット上で荷崩れすることが考えられる。特に、上部から下部にかけて若干のテーパーが形成されている電槽箱本体を使用する場合、パレット上での荷崩れが顕著となる。
本発明は、上述した従来の技術が有する課題を解消し、複数の隣接する鉛蓄電池の電槽の外部側面に設けられたリブ同士の噛み合いを防止することができる鉛蓄電池を提供することを目的とする。 By the way, at the time of transportation, this type of lead acid battery is packed with a plurality of lead acid batteries arranged on a pallet and tightened and packed. However, since the vertical rib is formed so as not to protrude from the peripheral side surface of the battery case lid, the lead storage battery moves due to vibration during transportation and is provided on the outer side surface of the battery case body of the adjacent lead storage battery. It is conceivable that the vertical ribs enter between adjacent ribs and the ribs mesh with each other. When ribs of adjacent lead storage batteries mesh with each other during transportation, the adjacent battery case main bodies approach each other as much as the ribs mesh with each other. On the other hand, since the battery case lid that closes the opening of the battery case is formed in the standard size of the lead storage battery in a top view, even when the ribs of the adjacent lead storage batteries are engaged with each other, they are close to each other. There is nothing. Therefore, it is considered that the lower part of the battery case approaches the battery case lid between adjacent lead storage batteries, the lead storage battery tilts and collapses on the pallet. In particular, when using a battery case main body in which a slight taper is formed from the upper part to the lower part, the load collapse on the pallet becomes remarkable.
An object of the present invention is to provide a lead storage battery that solves the above-described problems of the prior art and can prevent meshing between ribs provided on the external side surfaces of a plurality of adjacent lead storage battery batteries. And

上記目的を達成するために、本発明は、電槽箱と、前記電槽箱の上部開口を塞ぐ電槽蓋とからなる電槽箱本体を備えた鉛蓄電池において、前記電槽箱本体の側面に縦方向に複数条に突出した縦リブを備え、前記突出した縦リブは前記電槽蓋の周側面より突出しないように形成され、且つ、隣接する前記縦リブ間を繋ぐ横リブを備え、前記電槽箱本体の一対の対向する側面には、その間に前記横リブを有する隣接する前記縦リブと、前記横リブを間に有しない隣接する前記縦リブとが設けられ、前記縦リブと前記横リブの配置は、前記電槽箱本体の前記横リブが形成された側面と、前記電槽箱本体と同一の他の電槽箱本体の前記横リブが形成された側面とを対向させて並べた場合に、前記横リブを有する隣接する前記縦リブと、前記横リブを間に有しない隣接する前記縦リブとが対向する配置とされることを特徴とする。 To achieve the above object, the present invention includes a battery container box, the lead-acid battery having a made battery container box body and a lid the container for closing the upper opening of the battery case box, the side surface of the battery container box body to comprise a longitudinal rib projecting into multiple strip longitudinally, said protruding longitudinal rib is formed so as not to protrude from the peripheral side surface of the battery container lid and comprises a lateral rib connecting between said longitudinal ribs adjacent, A pair of opposing side surfaces of the battery case main body are provided with the adjacent vertical ribs having the horizontal ribs therebetween, and the adjacent vertical ribs not having the horizontal ribs therebetween, and the vertical ribs, The arrangement of the lateral ribs is such that the side surface of the battery case main body on which the horizontal rib is formed faces the side surface of the other battery case main body that is the same as the battery case main body. The adjacent vertical ribs having the horizontal ribs and the horizontal ribs. No and adjacent said longitudinal ribs, characterized in that it is an arrangement opposite.

この構成によれば、複数の鉛蓄電池を並べて輸送する際に、輸送時の振動を受けて鉛蓄電池が横ずれをおこしても、隣接する鉛蓄電池の、一方の鉛蓄電池の縦リブを、他方の鉛蓄電池の横リブに干渉させることができ、縦リブ同士が噛み合うのを防止することができる。 According to this configuration, when transporting side by side multiple lead-acid battery, it is lead-acid battery receives vibration during transportation cause lateral displacement, of the adjacent lead-acid battery, the longitudinal ribs of one of the lead storage battery, the other It can be made to interfere with the horizontal ribs of the lead storage battery, and the vertical ribs can be prevented from meshing with each other.

この構成において、前記横リブを、鉛蓄電池の重心位置よりも低い位置に設けた構成としても良い。
この構成によれば、隣接する鉛蓄電池の縦リブ同士が噛み合うのを防止する横リブが、鉛蓄電池の重心位置よりも低い位置に設けられているため、鉛蓄電池１の輸送時に振動によって鉛蓄電池に傾く方向に力がかかった場合でも、鉛蓄電池の重心位置よりも低い位置に設けられた横リブを、隣接する鉛蓄電池の縦リブに干渉させて、鉛蓄電池が傾くのを防止することができる。 In this configuration, the lateral rib may be provided at a position lower than the position of the center of gravity of the lead storage battery.
According to this configuration, since the lateral rib for preventing the longitudinal ribs of the adjacent lead storage batteries from being engaged is provided at a position lower than the center of gravity of the lead storage battery, the lead storage battery is caused by vibration during transportation of the lead storage battery 1. Even when a force is applied in the direction in which the lead storage battery is tilted, it is possible to prevent the lead storage battery from tilting by interfering with the vertical rib of the adjacent lead storage battery at the position lower than the center of gravity of the lead storage battery. it can.

また、前記電槽箱本体の一対の対向する側面には、前記横リブが一本ずつ設けられ、一方の側面に設けられた横リブと他方の側面の端とに設けた横リブとは、当該鉛蓄電池の下面視或いは上面視で点対称の位置に設けられる構成としても良い。
この構成によれば、縦リブ間を繋ぐ横リブを電槽箱本体の側面の一部に設けて、縦リブ同士の噛み合いを防止することができる。また、横リブを部分スライドの金型で形成することができ、金型製造のコストを削減することができる。また、輸送時の振動を受けて、複数並べた鉛蓄電池が、隣接する鉛蓄電池に対して回転するのを防止することができる。また、点対称の位置に横リブを設けることで、隣接する鉛蓄電池の対向する面が１８０度回転した場合においても、横リブが、隣接する鉛蓄電池の縦リブと干渉する位置に配置される。そのため、輸送の際に、鉛蓄電池を並べる向きを考慮することなく、鉛蓄電池を載置することができるため、輸送作業の効率が向上する。
Further, the pair of opposing side surfaces of the battery case main body are provided with one horizontal rib, and the horizontal rib provided on one side and the side rib provided on the other side are: it may be provided on the bottom view or the position of the point symmetric in top view of the lead-acid battery.
According to this structure, the horizontal rib which connects between vertical ribs can be provided in a part of side surface of a battery case main body, and the meshing of vertical ribs can be prevented. Further, the lateral rib can be formed with a partial slide mold, and the cost of mold production can be reduced. Also, in response to vibration during transportation, more side-by-side lead-acid battery can be prevented from rotating relative to the adjacent lead-acid battery. Also, by providing the transverse rib to the position of point symmetry, in the case of opposed surfaces of the adjacent lead-acid battery is rotated 180 degrees, the transverse ribs, disposed to interfere with the longitudinal ribs of the adjacent lead-acid battery position The Therefore, since the lead storage battery can be placed without considering the direction in which the lead storage batteries are arranged during transportation, the efficiency of transportation work is improved.

本発明によれば、電槽箱本体の側面に縦方向に複数条に突出し設けられた縦リブの、隣接する縦リブ間を繋ぐ横リブを設けたため、複数の鉛蓄電池を並べて輸送する際に、輸送時の振動によって鉛蓄電池が横ずれを起こしても、隣接する一方の鉛蓄電池の縦リブが他方の鉛蓄電池の横リブに干渉し、隣接する鉛蓄電池の縦リブ同士が噛み合うのを防止することができるという効果を奏する。   According to the present invention, since the lateral ribs connecting the adjacent longitudinal ribs of the longitudinal ribs protruding in the longitudinal direction on the side surface of the battery case main body are provided, when transporting a plurality of lead storage batteries side by side, Even if the lead storage battery is laterally shifted due to vibration during transportation, the vertical ribs of one adjacent lead storage battery interfere with the horizontal ribs of the other lead storage battery and prevent the vertical ribs of adjacent lead storage batteries from meshing with each other. There is an effect that can be.

A plurality of vertical ribs 15 are provided. The vertical ribs 15 are provided over the battery case 11 from the bottom surface of the box portion 11B to the lower surface of the upper edge portion 11C.

各縦リブ１５の間隔は均等であっても良いし、或いは、不均等であっても良い。本実施形態においては、縦リブ１５が設けられていない側面２０Ａ及び側面２０Ｂからの距離がそれぞれ等しい一対の縦リブ１５，１５を、図２に示す鉛蓄電池１の正面視で左右対称に設け、各側面１７Ａ，１７Ｂに、４本の縦リブ１５を設ける構成とした。   The intervals between the vertical ribs 15 may be uniform or non-uniform. In the present embodiment, a pair of vertical ribs 15 and 15 that are equal in distance from the side surface 20A and the side surface 20B that are not provided with the vertical ribs 15 are provided symmetrically in a front view of the lead storage battery 1 shown in FIG. Four vertical ribs 15 are provided on each of the side surfaces 17A and 17B.

また、電槽箱１１の、縦リブ１５が設けられていない側面２０Ａ、或いは、側面２０Ｂに最も近い位置、つまり複数の縦リブ１５で、最端に設けられた縦リブ１５と、この最端の縦リブ１５の隣の縦リブ１５の間には、これらの一対の縦リブ１５，１５を繋ぐ横リブ１６が設けられている。横リブ１６は、縦リブ１５，１５と直交するように設けられている。横リブ１６は、図１に示すように、複数の鉛蓄電池１を並べて接続したときに、対向する縦リブ１５同士が噛み合うのを防止する。横リブ１６は、縦リブ１５と一体に形成され、鉛蓄電池１の重心位置Ｘよりも下方に設けられる。横リブ１６を、鉛蓄電池１の重心位置Ｘよりも下方に設けることで、上方に設けた場合より、更に傾く事を確実に防止できる。   Further, the side of the battery case 11 where the vertical rib 15 is not provided, or the position closest to the side 20B, that is, the plurality of vertical ribs 15, the vertical rib 15 provided at the end, and the end Between the vertical ribs 15 adjacent to the vertical ribs 15, horizontal ribs 16 that connect the pair of vertical ribs 15, 15 are provided. The lateral rib 16 is provided so as to be orthogonal to the longitudinal ribs 15 and 15.

The lateral rib 16 is formed by setting a partial slide called a slide core for forming the lateral rib 16 on a mold that forms the battery case 11. Thus, by making the horizontal rib 16 partial, the horizontal rib 16 can be formed by adopting a partial slide, and the cost of the mold for creating the battery case 11 can be reduced. .

縦リブ１５は、図３に示すように、電槽箱１１の外形寸法と、電槽蓋１２の上面視の外見寸法とをそろえるために設けられる。箱部１１Ｂは、箱幅Ｗ２に形成され、縦リブ１５は、リブ幅Ｗ３に形成される。縦リブ１５は、箱部１１Ｂの幅方向の前後に同じリブ幅Ｗ３で形成され、側面１７Ａ，１７Ｂから略直角に電槽箱１１の外部に向かって突出するように設けられている。縦リブ１５は、電槽箱１１と一体に形成され、電槽箱１１の強度を高めて、電槽箱１１の膨れを防止する効果も備える。   As shown in FIG. 3, the vertical ribs 15 are provided to align the outer dimensions of the battery case 11 and the outer dimensions of the battery case lid 12 when viewed from the top. The box part 11B is formed with a box width W2, and the vertical ribs 15 are formed with a rib width W3. The vertical ribs 15 are formed with the same rib width W3 before and after the box portion 11B in the width direction, and are provided so as to protrude from the side surfaces 17A and 17B toward the outside of the battery case 11 at a substantially right angle. The vertical ribs 15 are formed integrally with the battery case 11 and have an effect of increasing the strength of the battery case 11 and preventing the battery case 11 from swelling.

横リブ１６は、底面１１Ｄから上方に設けることが好ましい。この構成によれば、鉛蓄電池１が輸送時に縦方向の振動を受けて浮き上がった場合でも、縦リブ１５の底面が、隣接する鉛蓄電池１の横リブ１６の上に乗りあがるのを防止することができる。

Can do.
Although not shown, the vertical rib 15 below the horizontal rib 16 may be obliquely cut from the bottom surface 11 </ b> D of the battery case 11 toward the horizontal rib 16.
According to this configuration, even when the lead storage battery 1 is lifted by receiving vibration in the vertical direction during transportation, the bottom surface of the vertical rib 15 that is diagonally cut off rides on the horizontal rib 16 or the top surface of the horizontal rib 16. It is possible to prevent the vertical ribs 15 or the horizontal ribs 16 of the adjacent lead storage batteries 1 from engaging with each other without entering.

図４に示すように、縦リブ１５は、側面２０Ａ或いは側面２０Ｂからの間隔が同じになるように、一対の対向する側面１７Ａ，１７Ｂと一体に設けられている。ところで、図４において、電槽箱本体１０の下面から遠方に見える電槽箱１１の上縁部１１Ｃは、図中に横リブ１６を示すために破線で示した。
横リブ１６は、側面１７Ａ側、及び、側面１７Ｂ側にそれぞれ設けられ、側面１７Ａ側の横リブ１６と、側面１７Ｂ側の横リブ１６とは、鉛蓄電池１の下面視或いは上面視で、点対称の位置に設けられている。横リブ１６の幅、及び、縦リブ１５の幅はともに上述のリブ幅Ｗ３に形成されている。 As shown in FIG. 4, the vertical rib 15 is provided integrally with a pair of opposing side surfaces 17A and 17B so that the distance from the side surface 20A or the side surface 20B is the same. Incidentally, in FIG. 4, the upper edge portion 11 </ b> C of the battery case 11 that can be seen from the lower surface of the battery case body 10 is indicated by a broken line in order to show the lateral ribs 16.
The lateral ribs 16 are provided on the side surface 17A side and the side surface 17B side, respectively, and the lateral ribs 16 on the side surface 17A side and the lateral ribs 16 on the side surface 17B side are points in the bottom view or the top view of the lead storage battery 1. It is provided at a symmetrical position. Both the width of the horizontal rib 16 and the width of the vertical rib 15 are formed to the above-described rib width W3.

図５は、鉛蓄電池１Ａ、１Ｂを、側面１７Ａ、或いは、側面１７Ｂが対向するように並べた状態を示す下面図である。図５においても、図４と同様に、電槽箱本体１０の下面から遠方に見える電槽箱１１の上縁部１１Ｃは、図中に横リブ１６を示すために破線で示した。鉛蓄電池１は、上述のように何十個あるいは何百個つなげて使用することが可能であり、鉛蓄電池１の輸送時には、多数の鉛蓄電池１を不図示のパレットに積載して輸送する。   FIG. 5 is a bottom view showing a state in which the lead storage batteries 1A and 1B are arranged so that the side surface 17A or the side surface 17B faces each other. Also in FIG. 5, similarly to FIG. 4, the upper edge portion 11 </ b> C of the battery case 11 that is visible from the lower surface of the battery case body 10 is indicated by a broken line in order to show the lateral ribs 16. The lead storage battery 1 can be used by connecting dozens or hundreds as described above. When the lead storage battery 1 is transported, a large number of lead storage batteries 1 are loaded on a pallet (not shown) and transported.

横リブ１６，１６は、上述したように、側面１７Ａ，１７Ｂの互いに点対称の位置に設けられている。そのため、鉛蓄電池１を並べた時に、鉛蓄電池１Ａの側面１７Ａに対向する、鉛蓄電池１Ｂの側面が、側面１７Ａであっても、或いは、側面１７Ｂであっても、図５に示すように、横リブ１６が設けられた一対の縦リブ１５，１５と、横リブ１６を間に介さない一対の縦リブ１５，１５が対向する。   As described above, the lateral ribs 16 and 16 are provided at positions that are point-symmetric with respect to the side surfaces 17A and 17B. Therefore, even if the side surface of the lead storage battery 1B facing the side surface 17A of the lead storage battery 1A when the lead storage battery 1 is arranged is the side surface 17A or the side surface 17B, as shown in FIG. The pair of vertical ribs 15, 15 provided with the horizontal rib 16 and the pair of vertical ribs 15, 15 that do not interpose the horizontal rib 16 face each other.

そのため、鉛蓄電池１Ａの縦リブ１５，１５の間に、鉛蓄電池１Ｂの縦リブ１５，１５が入り込むことがなく、縦リブ１５同士が互いに噛み合うのを防止することができる。これによって、鉛蓄電池１を輸送のためにパレットに積載する際に、隣接する鉛蓄電池１同士の向きを考慮することなく並べても、隣接する鉛蓄電池１間で、輸送時の振動等によって縦リブ１５同士が噛み合うのを防止することができるため、輸送時に各鉛蓄電池１を正規な姿勢に保つことができる。   Therefore, the vertical ribs 15 and 15 of the lead storage battery 1B do not enter between the vertical ribs 15 and 15 of the lead storage battery 1A, and the vertical ribs 15 can be prevented from meshing with each other. Thus, when the lead storage batteries 1 are loaded on a pallet for transportation, even if they are arranged without considering the direction of the adjacent lead storage batteries 1, vertical ribs are caused between the adjacent lead storage batteries 1 due to vibration during transportation or the like. Since 15 can be prevented from being engaged with each other, each lead storage battery 1 can be kept in a normal posture during transportation.

また、横リブ１６は、各側面１７Ａ，１７Ｂの最端の縦リブ１５と、最端の縦リブ１５の隣の縦リブ１５と、の間に形成されているため、鉛蓄電池１Ａが隣接する鉛蓄電池１Ｂに対して回転するのを防止することができ、複数の鉛蓄電池１を輸送する際に、各鉛蓄電池１を正規な姿勢に保つことができる。 The horizontal ribs 16, each side 17A, the vertical ribs 15 of the top end of the 17B, because it is formed between the longitudinal ribs 15 of adjacent longitudinal ribs 15 of the top end, a lead-acid battery 1A is adjacent It can prevent rotating with respect to the lead storage battery 1B, and when transporting a plurality of lead storage batteries 1, each lead storage battery 1 can be maintained in a normal posture.

以上説明したように、本実施形態によれば、電槽箱本体１１Ｂの側面１７Ａ，１７Ｂに設けられた複数条の縦リブ１５の、隣接する縦リブ１５，１５間を繋ぐ横リブ１６を設けたため、複数の鉛蓄電池１を並べて輸送する際に、輸送時の振動によって鉛蓄電池１が横ずれを起こしても、隣接する鉛蓄電池１の一方の鉛蓄電池１Ａの縦リブ１５が他方の鉛蓄電池１Ｂの横リブ１６に干渉させて、隣接する鉛蓄電池１の縦リブ１５，１５同士が噛み合うのを防止することができる。 As described above, according to the present embodiment, the horizontal ribs 16 connecting the adjacent vertical ribs 15 and 15 of the plurality of vertical ribs 15 provided on the side surfaces 17A and 17B of the battery case main body 11B are provided. Therefore, when a plurality of lead storage batteries 1 are transported side by side, even if the lead storage battery 1 is laterally shifted due to vibration during transport, the vertical rib 15 of one lead storage battery 1A of the adjacent lead storage battery 1 is the other lead storage battery. By interfering with the 1 B horizontal ribs 16, it is possible to prevent the adjacent vertical ribs 15, 15 of the lead storage battery 1 from meshing with each other.

また、本実施形態によれば、隣接する鉛蓄電池１の縦リブ１５同士が噛み合うのを防止する横リブ１６が、鉛蓄電池１の重心位置Ｘよりも低い位置に設けられているため、鉛蓄電池１に輸送時に振動によって傾く方向に力がかかった場合でも、鉛蓄電池１の重心位置Ｘよりも低い位置に設けられた横リブ１６が隣接する鉛蓄電池１の縦リブ１５と干渉して、隣接する鉛蓄電池１の縦リブ１５同士が噛み合うことがなく、鉛蓄電池１が傾くのを防止することができる。   Moreover, according to this embodiment, since the horizontal rib 16 which prevents the vertical ribs 15 of the adjacent lead storage battery 1 from meshing is provided in the position lower than the gravity center position X of the lead storage battery 1, the lead storage battery. 1 even when a force is applied in a direction inclined by vibration during transportation, the horizontal rib 16 provided at a position lower than the gravity center position X of the lead storage battery 1 interferes with the vertical rib 15 of the adjacent lead storage battery 1 and The vertical ribs 15 of the lead storage battery 1 to be engaged do not mesh with each other, and the lead storage battery 1 can be prevented from tilting.

また、本実施形態によれば、横リブ１６を側面１７Ａ，１７Ｂの一部に設けることができるため、横リブ１６を部分スライドの金型で形成することができ、電槽箱１１を形成するための金型の製造コストを削減することができる。
また、横リブ１６を側面１７Ａ，１７Ｂの最端に設けたため、輸送時の振動を受けて、複数並べた鉛蓄電池１が、隣接する鉛蓄電池１に対して回転する方向に力を受けても、横リブ１６が、隣接する鉛蓄電池１の縦リブ１５と干渉して、鉛蓄電池１が回転するのを防止することができる。
また、鉛蓄電池１の側面１７Ａと、側面１７Ａと対向する側面１７Ｂで、互いに点対称の位置に横リブ１６を設けたため、隣接する鉛蓄電池１の対向する面が側面１７Ａ，１７Ａ同士の場合、或いは、一方の鉛蓄電池１Ａが１８０度回転した、側面１７Ａと側面１７Ｂの場合のどちらにおいても、横リブ１６が、隣接する鉛蓄電池１Ｂの、横リブ１６を間に有しない縦リブ１５、１５と干渉する位置に配置される。そのため、輸送の際に、鉛蓄電池１を並べる向きを考慮することなく、鉛蓄電池１を載置することができるため、輸送作業の効率が向上する。 Moreover, according to this embodiment, since the horizontal rib 16 can be provided in a part of side surface 17A, 17B, the horizontal rib 16 can be formed with the metal mold | die of a partial slide, and the battery case 11 is formed. Therefore, the manufacturing cost of the mold can be reduced.
In addition, since the lateral rib 16 is provided at the extreme end of the side surfaces 17A and 17B, even if the lead storage batteries 1 arranged in parallel receive a force in the direction of rotation with respect to the adjacent lead storage batteries 1 due to vibration during transportation. The lead ribs 1 can be prevented from rotating due to the horizontal ribs 16 interfering with the vertical ribs 15 of the adjacent lead acid batteries 1.
In addition, since the lateral rib 16 is provided at a point-symmetrical position on the side surface 17A of the lead storage battery 1 and the side surface 17B facing the side surface 17A, the opposing surfaces of the adjacent lead storage battery 1 are the side surfaces 17A and 17A. Alternatively, one of the lead-acid battery 1 a is rotated 180 degrees, in either case side 17A and side 17B also, the transverse ribs 16, adjacent the lead-acid battery 1 B, the vertical ribs 15 having no between the transverse ribs 16 , 15 are arranged at positions that interfere with each other. Therefore, since the lead storage battery 1 can be placed without considering the direction in which the lead storage batteries 1 are arranged during transport, the efficiency of transport work is improved.

また、本実施形態によれば、横リブ１６を、電槽箱１１の底面１１Ｄから、縦リブ１５の幅Ｗ３の寸法分より上方に設けたため、鉛蓄電池１の輸送時に縦方向の振動を受けて、鉛蓄電池１が浮き上がった場合においても、隣接する鉛蓄電池１の、一方の鉛蓄電池１Ａの縦リブ１５の下面が、他方の鉛蓄電池１Ｂの横リブ１６の上に乗り上げるのを防止することができ、縦リブ１５同士が噛み合うのを防止することができる。 Further, according to the present embodiment, the horizontal rib 16 is provided above the bottom surface 11D of the battery case 11 above the dimension of the width W3 of the vertical rib 15, so that it receives vertical vibration during the transportation of the lead storage battery 1. Te, even when the lead-acid battery 1 is lifted, preventing the lead storage battery 1 adjacent, that the underside of the longitudinal ribs 15 of one of the lead storage battery 1 a is rides over the transverse rib 16 of the other of the lead storage battery 1 B It is possible to prevent the vertical ribs 15 from meshing with each other.
